Description

  The present invention relates to a corrugated sheet presser used for, for example, corrugated sheets.

Technical background

  Conventionally, a corrugated plate retainer is generally used when attaching a corrugated crest formed by a crest and a trough to a member that forms a framework such as a torso or a pier. Then, a mounting hole is opened in the peak portion of the corrugated plate, and after inserting the column portion of the corrugated sheet pressing tool into the mounting hole, the corrugated plate is attached so that the hook portion is put on a member that becomes a framework.

  As examples of such corrugated plate holders, for example, the following are known. (See Patent Document 1)

  Furthermore, in such a corrugated sheet pressing tool, for example, the corrugated sheet pressing tool main body column is formed in a bolt shape and a nut is screwed so that the corrugated sheet and the frame member are more difficult to separate. There are known products that have been devised to increase the strength. (See Patent Document 2)

  However, in order to make such a corrugated plate retainer generally difficult to break, for example, when removing a corrugated plate in a work such as remodeling or dismantling of a building or the like, it cannot be easily removed. There was a problem that unnecessary time and labor were required, and a reaction that applied extra force during removal caused the corrugated sheet to break and the operator to be injured by fragments.

  Moreover, the thing which made the pillar part of the corrugated plate holder main body a bolt shape, and strengthened the strength by screwing the nut, the strength becomes stronger, but the building etc. When removing a corrugated sheet from a framework member, such as remodeling or dismantling, it becomes more difficult to remove, for example, screwed bolts and nuts must be removed one by one. There is a problem that it takes a lot of time and labor.

  Therefore, the problem to be solved by the present invention is that, for example, when a corrugated sheet in a work such as remodeling or dismantling of a building is removed from a member that becomes a framework, it can be easily removed and wasteful time and labor can be saved. The present invention is to provide a corrugated sheet presser that is capable of preventing the operator from being injured without causing a reaction of removal and without generating broken corrugated fragments.

  In order to solve the above-described problems, the invention of claim 1 is provided with a hook portion that is bent obliquely upward at the lower end of the column portion, and the flange protruding from the periphery of the column portion at the upper end of the column portion. In the corrugated plate pressing tool provided with the head portion provided with the projection portion protruding above the upper surface side of the head portion and the flange portion, a configuration in which the weak portion is provided at the connecting portion between the head portion and the column portion is adopted. Is.

According to a second aspect of the present invention, in the corrugated plate pressing tool according to the first aspect, a configuration is adopted in which the fragile portion is a small diameter portion having a diameter smaller than the axial diameter of the column portion.

The invention of claim 3 employs a configuration in which a hollow portion is provided inside the fragile portion in the corrugated sheet presser according to claim 1.

  According to the present invention, for example, when removing a corrugated sheet from a member such as a frame in a work such as remodeling or dismantling of a building or the like, it can be easily removed, and wasteful time and labor can be saved. Moreover, there is no reaction of removal, no broken corrugated pieces are generated, and the operator is not injured.

  A hook portion bent obliquely upward is provided at the lower end of the column portion, and a flange portion protruding in a hook shape from the periphery of the column portion and a protruding portion protruding above the upper surface side of the flange portion are provided at the upper end of the column portion. In the corrugated plate pressing tool provided with the head portion provided, the corrugated plate pressing tool is provided with a fragile portion at a connecting portion between the head portion and the column portion, and a hollow portion provided inside the fragile portion.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of the corrugated sheet pressing tool of the present invention.

  In FIG. 1, a hook portion 2 that is bent obliquely upward is provided at the lower end of the column portion 1, and a flange portion 3 that protrudes in a hook shape from the periphery of the column portion 1 at the upper end of the column portion 1. In the corrugated plate pressing tool provided with the head portion 5 provided with the protruding portion 4 protruding upward from the upper surface side, a fragile portion 7 is provided at the connecting portion 6 between the head portion 5 and the column portion 1, and the fragile portion 7 Is formed in a small diameter shape that is thinner than the axial diameter of the column portion 1.

  When using this corrugated plate retainer to mount the corrugated crest formed by the crest and trough to a member that forms a framework such as a torso or pier, the corrugated crest Drill the mounting hole using a tool such as a drill or drilling tool. And after inserting the column part 1 of a corrugated sheet pressing tool in this attachment hole, a corrugated sheet is attached so that the hook part 2 may be applied to the member used as a framework.

  When the corrugated sheet pressing tool is inserted into a hole or applied to a member that is a framework, a force acts in the axial direction of the column part 1, that is, the vertical direction in FIG. It will not break or break with little effect on the strength.

  Moreover, examples of the event that causes the corrugated sheet to be detached from the members that form the framework after the construction of the building or the like is completed include natural disasters such as typhoons and earthquakes.

  However, with wind pressure such as typhoon, it is known that, for example, when a roof is considered, a pulling force generally works in the vertical direction of the roof plane. In addition, in the vibration force due to vibrations such as earthquakes, horizontal force generally works on heavy roofing materials such as tiles, but horizontal force hardly works on lightweight roofing materials such as corrugated sheets. It is known that a vibration force works in the vertical direction of the roof plane.

  Therefore, for example, in the case of a roof, even in the case of a typhoon or an earthquake, the wave pressing member is acted on in the axial direction of the column part 1, that is, the vertical direction in FIG. It hardly breaks or breaks without affecting the strength of the presser.

  When remodeling or dismantling a building, etc., humans remove the corrugated board from the framework using hands or tools, or remove the corrugated board using machinery or heavy machinery. Or

  When a human removes a corrugated sheet, for example, when considering the roof, a method of removing the corrugated sheet upward in the roof or a method of removing the corrugated sheet in a direction horizontal to the roof surface can be considered. When removing corrugated plates upwards, humans go up to the roof and remove them one by one. At this time, since the corrugated plate is firmly attached to a member to be a framework, there is a drawback that it is necessary to apply an extra force. For this reason, the corrugated sheet breaks due to excessive force applied, and even if it is intended to reuse the corrugated sheet, it cannot be reused, and the recoil after removing the corrugated sheet will cause it to fall off the roof. There are disadvantages such as being injured by being in danger of falling or falling, or accidentally touching a broken corrugated cut.

  For this reason, generally, a method is adopted in which a stepladder or a ladder is applied to the roof, or a scaffold is provided near the roof, and the corrugated sheet is removed in a horizontal direction on the roof surface. At this time, if the strength of the corrugated plate retainer is too strong in the horizontal direction of the roof surface, that is, the horizontal direction of the corrugated plate retainer, the disadvantage that the corrugated plate cannot be removed without applying extra force. There is. For this reason, the corrugated sheet breaks due to excessive force applied, and even if it is intended to reuse the corrugated sheet, it cannot be reused, and the recoil after removing the corrugated sheet will cause it to fall off the roof. There are disadvantages such as being injured by being in danger of falling or falling, or accidentally touching a broken corrugated cut.

  However, when the weakened portion 8 is provided in the connecting portion 7 so as to be broken at an appropriate strength with respect to the horizontal direction of the corrugated plate holder, an appropriate force is applied when removing the corrugated plate in the horizontal direction on the roof surface. As it is added, naturally the force is applied to the weak part, so it naturally concentrates on the weak part 7. When the force concentrates on the fragile portion 7 to some extent, the fragile portion 7 is divided and broken into the pillar portion 1 and the head portion 5. That is, the column part 1 and the head part 5 are divided and broken by a smaller force than when the fragile part 7 is not provided. Therefore, the corrugated sheet can be easily removed without applying extra force. For this reason, it is not necessary to apply extra force, and there is no large hole in the corrugated plate by the hook part 2 of the corrugated plate presser, or the breakage or breakage of the corrugated plate caused by applying excessive force. Because the corrugated sheet can be reused and the resources can be reused, the result is that it is easy for the environment, and the risk of falling off the roof due to the reaction of removing the corrugated sheet There is an advantage that work can be done safely without worrying about injury by touching a broken corrugated sheet by mistake.

  In FIG. 1, for example, the fragile portion 7 has a configuration in which the diameter thereof is narrower than that of the column portion 1, but the fragile portion 7 is provided inside the connecting portion 6 as illustrated in FIG. 2, for example. Also good. FIG. 3 shows an AA ′ cross-sectional view of the second embodiment in which the fragile portion 7 is the hollow portion 17. In addition to this, the fragile portion 7 has, for example, a ring-shaped cut shape, a V-shaped groove shape, or any structure that breaks and breaks by adding an appropriate strength from the lateral direction of the column portion 1. It does not matter if it is shaped like this. A plurality of such hollow portions 17 may be provided. Moreover, although the shape of the cavity part 17 is spherical, for example, it is a cavity like an egg shape, a cavity of a polyhedron shape, or a structure in which an appropriate strength is applied from the lateral direction of the pillar part 1 to break it. Any shape is acceptable as long as it is.

  1, 2, and 3, for example, a configuration in which the fragile portion 7 is provided in the connecting portion 6 is illustrated. However, the fragile portion 7 may be provided closer to the flange portion 3 than the connecting portion 6 as illustrated in FIG. 4, for example. 5 may be provided closer to the column part 1 than the connecting part 6. In addition to this, the fragile portion 7 has, for example, a ring-shaped cut shape, a V-shaped groove shape, or any structure that breaks and breaks by adding an appropriate strength from the lateral direction of the column portion 1. It does not matter if it is shaped like this. And such a weak part 7 may be divided and provided. Moreover, although the shape of the cavity part 17 is spherical, for example, it is a cavity like an egg shape, a cavity of a polyhedron shape, or a structure in which an appropriate strength is applied from the lateral direction of the pillar part 1 to break it. Any shape is acceptable as long as it is.

  As described above, for example, when removing a corrugated sheet from a member such as a frame in a work such as remodeling or dismantling of a building, etc., the fragile part 7 of the corrugated sheet presser is broken with an appropriate strength. Therefore, it can be easily removed and wasteful time and labor can be saved. In addition, since it is not necessary to apply extra force, the corrugated sheet is not broken, and the corrugated sheet can be reused and resources can be reused. In addition, there is no danger of falling off the roof due to the reaction of removing the corrugated sheet, and there is no danger of falling, and by accidentally touching the broken corrugated cut, work without worrying about injury Can be done safely.
